user may fix stuck pixels,
works on mobile phones and other portable devices with Java support.

People with epilepsy shouldn't use this program.

Stuck and dead pixels

Stuck pixels are pixels which are lighten when they shouldn't be. The easiest way to find them is to display black screen on a monitor. If, on a black screen, there is a pixel which has a color, it's red for instance, it's a stuck pixel.
Dead pixels are pixels which are black, no matter what is displayed on the screen. The easiest way to find them is to display white screen on a monitor. If, on a white screen, there is a black pixel, it's dead pixel.
PixelRepairer program fixes stuck pixels by applying high frequency color change.

Searching for stuck pixels

To find stuck pixels you must:

Clean the device's LCD display.
Run PixelRepairerMobile.
Select language, 'English' for instance.
Select 'Search'.
Select black color on patterns list.
Check, if any of pixels has color different than black. If so, it's stuck pixel.
Disable the test by pressing any key.

You may switch patterns by pressing 2, 4, 6 or 8 keys.
If a stuck pixel or some stuck pixels were found you may repair them.

Repair stuck pixels

To repair stuck pixels you must:

Run PixelRepairerMobile.
Select language, 'English' for instance.
Select 'Repair'.
Set prefered mode of operation.
Set repair frequency. In the case you're not sure what frequency should be set, just leave 30Hz.
Wait about an hour.

Checking and Fixing DP (read : Dead Pixel) for
LCD Monitor

This tips maybe useful for all LCD Screen Monitor, its happen after long time usage and the screen just showing light without any sign that we can see any changes in screean display, so that makes the LCD Screen becomes in low performance quality. Dot sign in that screen ussually was broke, and we can call it DP or Dead Pixel or Stuck Pixel, how we know about that, and if that showed, how to fix that ?

Let's start....

Identified / Checking Dead Pixel

The point of checking about that DP actually can be an easy way, but sometimes we've got panic first and then think fast to sell that "things"..But we can try to identified or checking that LCD by knowing and seeing what happen to that screen, is there any dot that showing unblinking and just showing one kind of colours such as black or white, if we see that thing, so we must try to use this kind of software..it called Pixel Repairer.

Pixel Repairer's features:

helps in search of damaged pixels,
user may create and set repairing areas which will fix stuck pixels,
user may not stop using the computer while the monitor is repaired,
it takes small amount of hard drive and memory, and starts fast,
doesn't require installation of additional libraries or run-time environments,
can handle many monitors connected to the computer.

About PixelRepairer

PixelRepairer may be used to search for and repair of defective LDC monitor or plasma tv pixels. User may display test screens on any monitor or tv connected to the computer. It makes search of malfunctioning pixels easy. If you found stuck pixels, you may repair them. The repair is based on setting of small repairing area in place where stuck pixel were found. There is no need to stop using the computer while the screen is fixed. PixelRepairer working in background is repairing the monitor by itself while you are for instance surfing the Internet.

Searching for stuck pixels

To find stuck pixels you must:

Clean the monitor.
Run the Pixel Repairer program.
If the search panel isn't active, you must click on the 'Search' button. It's a button with a magnifying glass picture.
If a few monitors are connected to the computer, you may choose the monitor, which is going to be tested.
Choose black color on patterns list.
Click "Enable" button.
Check, if any of pixels has color different than black. If so, it's stuck pixel.
Disable the test by right clicking on the screen or pressing of the 'Esc' key.

If a stuck pixel or some stuck pixels were found you must remember it's position. Now, you may repair it.

Repair stuck pixels

To repair stuck pixels you must:

Run Pixel Repairer program.
If the repair panel isn't active, you must click on the "Repair" button. It's a button with a sticking plaster picture.
Add repairing area, so called "Repairer" by clicking the "Add" button.
Drag the Repairer in the place, where the stuck pixel or pixels were found.
Set prefered mode of operation.
Set Repairer's size. It should embrace the stuck pixel or pixels.
Set Repairer's frequency equal to monitor's frequency. In the case you're not sure what frequency should be set, just leave 60Hz.
If stuck pixels are present in the other area of the screen you may add another repairing area.
Minimize the program window.
Wait about an hour.[if you lucky...hmmmm : P]

Direct-X Versus Open-GL 2nd Part

Mr.K

So here is where I answer some of the big questions:

What is the difference between DirectX and OpenGL? The answer to this one is: everything. OpenGL was designed ages ago (pre 1990), while DirectX 1 was build (1994) specifically to draw game developers from DOS onto the new Windows 95 platform. DirectX is (to all intensive purposes) a Windows / Mircrosoft only solution, while OpenGL runs on most desktop operating systems that exist (including a variety of embedded platforms). While DirectX provides strong support for many features outside of 2D and 3D Graphics, OpenGL relies on external systems to provide that functionality (potential systems include: SDL, OpenAL, GLUT (OpenGL Utility Toolkit), or even DirectX).

What does DirectX Compatible mean? When a graphics card is DirectX 9 Compatible, it means that it supports the DirectX 9 specification and can run software built to run on top of DirectX 9. Due to it’s history, each version of DirectX breaks compatibility with the previous version. As a devloper, I see this as a nightmare for Microsoft and the developers that work with DirectX. Mainly for a developer: if you are qualified in DirectX 10, you need to learn how to drive DirectX 11.

Why is there only OpenGL 1 and 2? Considering that OpenGL is the older of the two, these numbers make OpenGL seem way out of date. The simple answer to this question is: Extensions. Where DirectX revises the entire platform with each release to incorporate new features, OpenGL has a system called Extensions. This allowed graphics card vendors to add new functionality without changing OpenGL itself. Those applications and games that needed the Extension can look ask the OpenGL system for the Extension, if it doesn’t exist: the game can work around not having the Extension, or explain to the user that their graphics card cannot support it. Major Extensions in recent years include:

Multitexturing
Normal Mapping
Shaders

Why is there no such thing as an “OpenGL compatible” graphics card? Again the answer is Extensions. Because the core OpenGL specification is so simple, almost any graphics card that is capable of any 3D graphics is OpenGL compatible. For that reason, no-one bothers with the idea of “OpenGL Compatible”.

What are DirectX and OpenGL?

Most people have no clue as to what DirectX or OpenGL actually is. Most people know DirectX as “the thing I need to run my games”. I felt it was time to write an explanation that clears up exactly what DirectX and OpenGL are. Below is a simple “stack” diagram to show how the layers between your Graphics Card (NVidia; ATI; Via; Intel; S3; etc.), and your Games fit together:

Going from the bottom layer (your hardware), to the top layer (your Games): the first layer is the “Hardware Abstraction Layer”. This layer is provided by the Operating System (Windows, Linux or Mac OS), and allows Device Drivers to “talk” to the hardware by sending and receiving data and commands. It’s a bit like your web browser sending and receiving data to a web site on the internet. However, each graphics chipset has a different protocol (think of it like a language) that it understands. Thats where the Device Driver layer comes in. The Operating System defines a set of standard language and set of commands that the Device Driver must provide to the Operating System. The Device Driver is responsible for translating those “Operating System Commands” into a the protocol that the actual Graphics Card can understand. A bit like a human translating between two languages.

However, generally a Graphics Device Driver for an Operating System generally has a very minimal set of commands for basic 2D operation (things like “draw this picture over here”; “draw a line here”; etc.), because there are still many graphics cards in the world that don’t support the complex operations expected by an advanced 3D Game. To compensate for that, DirectX and OpenGL provide an extended set of commands for doing complex 3D operations (like “draw a polygon”; “move the camera like this”; etc.).

Why make the Graphics Hardware do this? Having Hardware perform an operation is almost always faster than having software do it, thus the term “3D Hardware Acceleration”. DirectX and OpenGL give software (like Games, a level editor, or a 3D modeling package) access to the more advanced features a Graphics Card may provide. You might think of them as an “Advanced Device Driver”. But :
